public static RevisionControlled upgradeObject (RevisionControlled object) {
RevisionControlled reviseObject = null;
String foldername = object.getLocation();
WTContainerRef cabref = null;
if (object instanceof WTContained)
      cabref = ((WTContained) object).getContainerReference();
if (cabref != null) {
      try {
          object = (RevisionControlled)VersionControlHelper.service.newVersion(object);
          Folder folder = FolderHelper.service.getFolder(foldername,cabref);
          FolderHelper.assignLocation(object, folder);
          reviseObject = (RevisionControlled)PersistenceHelper.manager.save(object);
      } catch (WTException e) {e.printStackTrace();
      } catch (WTPropertyVetoException e) {
          e.printStackTrace();}}
return reviseObject;
}
